Dear Sir or Madam,

I recently upgraded my home server mainboard (Gigabyte K8NNXP-940) with a dual core processor AMD Opteron 275. Everything runs great, the BIOS recognizes the CPU and prints the correct CPU name string while booting. However, I cannot use the 2nd CPU core, although dmesg writes:

[ 0.000000] Scanning NUMA topology in Northbridge 24
[ 0.000000] CPU has 2 num_cores

Curiously, I was looking for the reason and found out that my BIOS' MADT/APIC table lacks the entry for the LAPIC of the 2nd core. I checked the manufacturer's website for BIOS updates, but of course there are not any :(

Just to test things out, I also installed windows xp and opensolaris. The former runs fine, though again with one core only, the latter crashes / reboots while booting.

After I found some information about loading custom DSDTs and SSDTs at
http://gaugusch.at/kernel.shtml

I rewrote my MADT table to make use of the 2nd core. However I recognized later, while browsing through the ACPI specifications on acpi.info that DSDT and SSDT do not include the MADTs :(

Please let me know if there is any possibility to load a custom MADT and/or if there is anything else I could do.

Thank you very much

Alex

dmesg ( please ignore the autoloaded DSDT, the result without it is the same :( )
